GAS STOVE.

Specification of Letters Patent. Pat nt ed Feb. 14 1922 Application. filed March 2 1921. Serial No. lf18,97.

To aZZ 10/ 10711 it may concern:

Be 1t known that I, THOMAS E. 001), a

citizen of the United States, residing at Amarillo, in the county of Potter and State of Texas, have invented new and useful Improvements in Gas Stoves, of which the following is a specification.

The object of my present invention is to provide a gas stove in which simple, inexpensive, durable and reliable I provision is made for varyingthe quantity of air commingled with thegas to suit the quality or character of the gas, this with a view to assuring complete or perfect combustion of the gas so as to utilize all of the heat values of the gas and avert the giving elf of riders.

To the attainment ofthe foregoing, the invention consists in the improvement as hereinafter described and definitely claimed.

In the'accompanying drawings, forming part hereof Figure 1 is a perspective of a gas stove, with a part broken away to better illustrate my invention.

Figure 2 is an enlarged detail longitudinal vertical section illustrative of my improvement.

Figures 3 and 4: are vertical transverse sections taken in the planes indicated by the lines and 4-4-, respectively, of F igure 2.

Figure 5 is a fragmentary horizontal section taken in the plane indicated by the line 5-5 of Figure 3.

Figures 6, 7 and 8 are detail views of a modification of my invention; Figure 7 being a" vertical transverse section on the line 7--7 of igure 6.

Similar numerals designate corresponding parts in Figures 1 to 5 to which reference will first be made. In general the gas stove is of the ordinary well known construction, being provided with a casing 1 and a batiie or heat radiating plate 2.

Carried by a vertically adjustable, horizontal wall 4 or other appropriate means in the casing 1 is a battery of tubular gas burners 5, the said burners being upright and open at their upper and lower ends and arranged in a longitudinal series as will be readily understood by comparison of Figures 1, 2 and 3. The said burners are preferably extended through and guided in a W113.

Extending longitudinally into the casing 1 through an opening 6 in one end wall thereof is a tubular manifold orgassupply pipe 7 the said manifold 7 being designed to be connected through avalved connection 8 with a source of ga'ssupplyf Atthe inner sides of the encbwalls of casing l and against the walls are arrangedfixed brackets 10 and 11, said brackets 10 and 11 being fixed to the said casing walls through the medium of headed andflthreaded bolts or screws 12. Each'the brackets 10 11 is of inverted T-configuration, and the bracket 10 is provided at'13 with an interiorly threaded sleeve for the reception and engagement of the threaded portion 14 of i the tubular manifold 7. is provided with a socket 15 interiorly threaded to seat the threaded end portion 16 of the tubular manifold. At points'in registration with the tubular burners 5 the tubular manifold 7 is provided with eduction-apertures 17 for gas; it beingfunde'rstood in this connection that when the gas is en route between the apertures 17 and the lower ends of the tubular burners 5, the gas will be commingled with airlet in any approved manner into the casing .1, so that the gas and "air will form highly combustible mixture. 'i i It frequently happens that both natural L and artificial gas vary in quality or character so that in some instances it isnecessary to locate the apertures 17 at a greater distance than that shown from the lower 5. To meet this condition it will be ob- The bracket 11 and induction ends of the tubiilar burners served that all that is necessary for the party in charge of my novel stove to do is to adjust. and position the burners 5 as desired relatively to the apertures 'l'f until changed conditions make another adjustment necessary. i

It will be observed by reference to Figure 5 that the lower wall 4 is provided with end bifurcations 18 and is guided on the brackets 10 and 11 to assure rectilinear up and down movements of the wall 4 and burner tubes 5 without subjecting the adjusting means to strain. g

In Figures 6, 7 and 8, I illustrate an embodiment in which the tubular manifold 7 like the manifold 7, is fixed with respect to the casing 1, and the tubular burners 5 are carried by a vertically adjustable wall or bar 4- and are arranged in and slidable through an upper wall or bar 3 The wall or bar 4: is flanged at its ends as indicated by l and the said flanges 45 are appropriately fixed with respect to brackets 10, the said'brackets 10 being adjustably fixed to the end walls of the casing 1 'through'the medium of threaded, headed and kerfed bolts 12 which are arranged in vertically elongated openings 9 in the end walls of the casing. Manifestly when the bolts 12 of Figure 6 are loosened through the medium of a screw driver, the brackets 10, the wall or bar 4- and the tubular burners 5? may be adjusted vertically so as to position the lower or induction ends of the tubular burners 5 at the desired distance from the eduction apertures 17 of the manifold 7.

For the purpose of adjusting and adjustably fixing the wall 4 and the burner tubes 5 carried by and movable with said wall 4, I provide upright adjusting screws 1.9, the heads 20 of which are disposed below the stove so that the adjustment referred to can be accomplished while the stove is lighted. The said screws 20 are located between and adjacent to the end walls of the casing 1 and are journaled in and held against endwise movement relatively to 30,

brackets 21, fixed with respect to the casing 1. The upper threaded portions of the screws 19 are extended through threaded apertures in the walls so that vertical movement oft-he wall a and the tubes 5 carried thereby will attend rotation of the screws 19.

Manifestly for small stoves a single, centrally-arranged screw 19 will suffice for adjusting and adjustably fixing the wall 4 and the tubes 5. This, however, I have deemed it unnecessary to illustrate.

Having described my invention, what I claim and desire to secure by Letters- Patent, is

1. In a gas stove, the combination of a casing or body, a tubular gas supply eouduit therein and having a plurality of eductiou apertures, a battery of tubular gas burners vertically adjustable in the casing or body and arranged with the burners in alinement with said apertures, and a screw bearing in means connected with the casing or body and engaging the battery of burners and having a finger piece or handle accessible at the bottom of the stove.

2. In a gas stove, the combination of a casing or body, a tubular manifold or gas supply pipe arranged in the casing or body and having a plurality of eduction aper tures, a battery of tubular gas burners also arranged in thecasing or body with the burners in alinement with the said apertures. brackets carrying said battery of burners, and arranged within the casing or body, and means adjustably fixing the said brackets with respect 'to the casing or body to adjustably fix the distance between the educ tion apertures of the tubular manifold and the tubular gas burners; said means including headed and threaded bolts bearing in the brackets and extending throughvertically elongated openings in opposite walls of the casing or body.

3. The combination in a gas stove, of a casing or body, brackets of inverted T-eonfiguration, arranged against the end walls of the casing 01' body and connected thereto,

.one of the said brackets having an interi- 4. In a gas stove,the combination of: a gas supply condult therein and having (KlllCtlOIl apertures at intervals in its length, a vertically-ad ustable horizontal bar guided in the casing and having threaded apertures upright burner tubes carried by and movable with said bar and alined with and arranged above said apertures, and upright screws bearing in and held against vertical movement by brackets fixed to the casing and extending through the threaded apertures of the bar and haviug finger pieces or haudles at their lower ends with brackets fixed 1n the casing and carrying said conduit and resting in bifurcations ofsaid bar to guide the latter. a V

In testimony whereof, I aflix my signature.
